Enabling High Availability Features

The fault tolerance and the high-availability features of Greenplum Database can be
configured.

Important: When data loss is not acceptable for a Pivotal Greenplum Database
cluster, master and segment mirroring must be enabled in order for the cluster to be
supported by Pivotal. Without mirroring, system and data availability is not guaranteed,
Pivotal will make best efforts to restore a cluster in this case. For information about
master and segment mirroring, see About
Redundancy and Failover.

For information about the utilities that are used to enable high availability, see the
Greenplum Database Utility Guide.

Overview of Greenplum Database High Availability
A Greenplum Database cluster can be made highly available by providing a fault-tolerant hardware platform, by enabling Greenplum Database high-availability features, and by performing regular monitoring and maintenance procedures to ensure the health of all system components.
